The Darlington Experiment

The Darlington Experiment was a scientific test conducted in the 1970s to investigate whether the universe had a preferred direction, which would suggest a violation of Lorentz invariance—a fundamental principle stating physical laws are the same in all directions and at all speeds. By analyzing cosmic ray data, researchers checked for any directional differences in particle behaviors. The results supported the idea that the universe is isotropic at large scales, confirming that physical laws are consistent regardless of viewing direction, thus reinforcing foundational principles of modern physics.
